Might I ask, how are the multiple slashes getting generated in the first place?
 Where is the data coming from?

Next question would be: Do you want to completely remove all instances of
multiple backslashes?  Or, do you want to replace all instances of multiple
backslashes with a single backslash?

I would try something like this:

<plaintext><?php

$in = '\\\as\\\\asdf\\\asdf\asdf\\\\\asdf\\\\\asdf';

# to remove all backslashes, us this
echo preg_replace('|[\\\\]+|', '', $in).PHP_EOL;

# to remove all backslashes, us this
echo str_replace('\\', '', $in).PHP_EOL;

# to replace consecutive instances of backslashes with a single backslash
echo preg_replace('|[\\\\]+|', '\\', $in).PHP_EOL;

?>
done!
